Company A is cheaper by
Company A costs $0.11 per minute.
Company B costs $0.13 per minute.

To find out how much a company charges per minute, for example, company A, take $132 and divide it by 1200, which gives you $0.11.

In △MNK MN = NK, m∠N = 110º, MK = 5. Find MN.

alexgriva [62]

Answer:

MN = 3.03 ≈ 3

Step-by-step explanation:

Given: In ΔMNK MN = NK , m∠N = 110° and MK = 5.

To find: MN = ?

Sol: In ΔMNK,

∠M + ∠N + ∠K = 180° (sum of angles of a triangle)

2∠M = 180° - 110° ( ∠M =∠K since MN = MK)

∠M = 70°/2 = 35°

∴ ∠M = ∠K = 35°

Now, Using Sine Rule for finding sides,

$\frac{m}{sinM} = \frac{n}{sinN} = \frac{k}{SinK}$

$\frac{k}{sinK} = \frac{n}{sinN}$

$\frac{5}{sin 110^{\circ}} = \frac{k}{sin 35^{\circ}}$

$k = \frac{5 sin 35^{\circ}}{sin 110^{\circ}}$

Now ∵ sin 35° = 0.57 and sin 110° = 0.94 approx.

By substituting these values in above expression,

$k = \frac{5 \times 0.57}{0.94}$

k = $\frac{2.85}{0.94}$

k = 3.03

Therefore, MN = 3 approx.
